125a circuit breaker
A 125A circuit breaker!
A 125A circuit breaker is a type of electrical device that is designed to protect electrical circuits from overcurrent and short-circuit conditions. Here are some key characteristics and uses of a 125A circuit breaker:
Ratings:
- Amperage rating: 125 amperes (A)
- Voltage rating: Typically 120/240 volts (V)
- Interrupting rating: 20,000 amps (A)
Applications:
- Residential and commercial electrical systems
- Main service entrance panels
- Sub-panels and branch circuits
- Industrial and commercial power distribution systems
Features:
- Thermal-magnetic trip mechanism: detects overcurrent and overheating conditions
- Arc-resistant design: helps to prevent arc flash and reduce the risk of electrical shock

Types:
- Molded case circuit breakers (MCCBs)
- Air circuit breakers (ACBs)
- Vacuum circuit breakers (VCBs)
- Arc-fault circuit breakers (AFCBs)
Benefits:
- Provides overcurrent protection and fault detection
- Reduces the risk of electrical shock and fire
- Easy to install and maintain
- Compact design saves space and reduces installation costs
Common uses:
- Main service entrance panels for residential and commercial buildings
- Sub-panels and branch circuits for industrial and commercial power distribution systems
- Industrial and commercial power distribution systems
Overall, a 125A circuit breaker is a reliable and efficient way to protect electrical circuits from overcurrent and short-circuit conditions, making it a popular choice for a wide range of applications.
